help wiring up old sub

Cyber-Mav · 7 Apr 2021 at 16:19

so i found this old sub in the shed and tested it with the phone using rca to phono cable and the sub does work.
no i know i can use it like this with a pc that has sub channel out but how can i use this with a regular tv? i do have a nvidia shield tv connected to the tv so wondering if there is some way to get this hooked up so i can get bass from the sub and the rest of the sound through the tv speakers?
sub is a philips sw 3800:

Odd it works perfectly with the pc. Also whats mono input got to do with it when it's a single speaker in the box.
Im guessing its gonna be a issue trying to integrate it into a digital audio setup that is hdmi.
Will have to think of something that's cheap, otherwise just cheaper and easier to get new sub.

You mentioned a yamaha sound bar, do sound bars in general have sub out which can work with this sub?
Iv never heard a sound bar most look small so i wondered if they are any better than the tv built in speakers.
Also iv never known bass to be in stereo.

Re-read the bit about the tank rumbling.

but if you only got 1 sub in the room how do you get stereo bass? not like people have 2 subs left and right.
low frequency sounds being omni directional etc.

That doesnt explain stereo bass. The example of the tank is talking about a stereo signal to a single sub but you cant do stereo with just a single speaker. Combined to mono is whats normally done.
So in your tank example the tank going from left to right how would that work with a single sub? Or does someone move the sub to the other side of the room when the tank exits ?

ok ignore all the stereo mono stuff.

i see the shield tv has a 3.5mm jack which i think is a output. can i use a 3.5mm jack splitter to send one cable to the tv and one to the sub then have volume on tv a max and sub volume at max then use the shield tv to control overall output volume?
i see there is a issue where someone changes source to cable box and gets an earful lol but is that doable? i dont know if playing content from shield tv outputs over hdmi or the 3.5mm jack?

From what iv read the physics of sound is that higher frequencies are more directional than low frequencies hence why stereo bass as such doesnt work as well as higher frequency sounds do.
Those expensive setups you shown look good but i still get the feeling they wont pump out bass like what iv heard in car audio with cars using 2x12 or 15inch subs with 1kw rms. But again i dont think stereo bass is a thing in a car since subs are so close to each other.

What happens if a sub is placed in front of you and one behind? Are those positions superior to having both subs in front left and right?

I just found the Philips sub in the shed so wondered it i could use it with what i have id like to get away from just using tv speakers.

What would you say is best value for money on the cheap side of things to get for speakers and sub?

Hmm i didn't think i would have had input from someone so clued up as you on this forum. This is the first time iv been on this music side of the forum.
Let me get some pics for you to show what im working with.

heres the pic of the room:

tv is a sharp 49 incher. have virgin cable box and nvidia shield tv and nintendo wii hooked up.
would like to put a sub behind the tv to get some bass when watching virgin box stuff and youtube stuff and from shield tv too.
